Abstract

An intrusion detection device and method in an IP connected security system is disclosed. An intrusion detection device is coupled to primary and secondary communication devices of a security system so that when a Internet attack is detected, communication between the security system and a central monitoring station occurs over the secondary communication device rather than the primary communication device. The invention preserves communication between the security system and the central monitoring station even when a denial of service type attack is occurring so that physical premise security is uncompromised.

Claims

1. A security system comprising:

a control panel;

sensors electrically coupled to said control panel;

a primary communication device for transmitting and receiving data;

a secondary communication device for transmitting and receiving data; and

an intrusion detection device coupled to said control panel,

wherein said intrusion detection device, upon detection of an intrusion, switches communication to said secondary communication device.

2. The security system of claim 1 wherein said intrusion detection device includes a firewall.

3. The security system of claim 1 wherein said primary communication device is a gateway router.

4. The security system of claim 1 wherein said primary communication device is a hub.

5. The security system of claim 1 wherein said primary communication device is a switch.

6. The security system of claim 1 wherein said control panel includes a display means.

7. The security system of claim 6 wherein said display means includes means for displaying a local alert.

8. The security system of claim 1 wherein said secondary communication device is a wireless dialer.

9. The security system of claim 1 wherein said secondary communication device is a telephone modem.

10. The security system of claim 1 wherein said intrusion detection device is configured for detecting packet intrusions to said security system.

11. A method of detecting intrusions to a securing a security system, said security system including a control panel;

sensors electrically coupled to said control panel;

a primary communication device coupled to said control panel for transmitting and receiving data;

a secondary communication device for transmitting and receiving data; and

an intrusion detection device coupled to said control panel, said method comprising the steps of;

at the intrusion detection device, detecting an intrusion attempt;

raising a local alert on said control panel; and

switching communication to said second communication device.

12. The method of claim 11 further comprising the step of disabling communication to said primary communication device.

13. The method of claim 11 wherein said intrusion detection device includes a firewall.

14. The method of claim 11 wherein said primary communication device is a gateway router.

15. The method of claim 11 wherein said primary communication device is a hub.

16. The method of claim 11 wherein said primary communication device is a switch.

17. The method of claim 11 wherein said control panel includes a display means.

18. The method of claim 17 wherein said local alert is displayed at said display means.

19. The method of claim 11 wherein said secondary communication device is a wireless dialer.

20. The method of claim 11 wherein said secondary communication device is a telephone modem.

21. The method of claim 11 wherein said intrusion detection device is configured for detecting packet intrusions to said security system.
